A given solid, of mass M, is heated to a temperature θ°C. It is put in contact with a large block of ice. It is known that a unit mass of ice needs L units of heat to just melt down. If the mass of ice, that just melts down, is m, the specific heat capacity, of the material of the solid, is
(1) mL/Mθ
(2) Mθ/mL
(3) ML/mθ
(4) mθ/ML
